I just got an old Sears Lathe. It's in pretty good shape, except for
some rust. (that I'm getting off now) The drive spur and live center
are both stuck... Any ideas about how to get them out so I can use
other accessories with my new (to me) lathe? I'm soaking them in
kroil. I'll see if they knock out in the moring. If not? Any ideas?
Thanks in advance.
There is a product, you can get it at your local NAPA auto parts store,
called "PB Blaster" which is extremely good on rust.
If that does not work, there is always heat. The downside of heat is the
results can vary widely between success and total failure.
I use a long bolt (custom made by myself) that locks in my Morse 4 or Morse 2
tools. It keeps the tool from coming out if I work against it while turning.
I use them to extract the tool - by un-screwing a couple of turns - leaving
a number of threads engaged and give it a rap with a rubber mallet.
Sometimes it takes a stronger go than that. But I have a shot filled mallet
before I get out something bigger.
I started bolting it in so when moving left to right without a tailstock
engaged the spur or else - doesn't disengage.
Something like a drift pin in function.
